Masha and Nadya made it clear last night that we have not heard the last of them.

Maria ‘Masha’ Alyokhina and Nadezhda ‘Nadya’ Tolokonnikova – members of the Russian protest punk band Pussy Riot – made their first public visit to the U.S. this week.

Their two-day tour of New York included a press conference at Amnesty International headquarters Tuesday, a hilarious interview on the Colbert Report Tuesday night, and an appearance at the Amnesty International “Bringing Human Rights Home” concert at the Barclays Center in Brooklyn last night.

Masha and Nadya were two of the three members of the band found guilty of ‘hooliganism’ for singing a protest song in Moscow’s Cathedral of Christ the Savior in 2012. They were sentenced to two years in a Russian penal colony following a trial that attracted significant international press attention, while shining a light on Russia’s precarious human rights record and president Vladimir Putin’s continued crackdown on political dissidents.

The pair were only released from prison this past December as part of an amnesty bill submitted by Putin. Many viewed the move as a cynical ploy by Putin to avoid additional bad press ahead of the 2014 Sochi Olympics.

In fact, Masha and Nadya’s appearance in the U.S. on the eve of the Winter Olympics is no coincidence. In their description of the concert Amnesty International specifically cited the Olympics as a motivating factor for the concert:

On the eve of the 2014 Sochi Olympics in Russia, thousands of human rights supporters will descend upon the Barclays Center in Brooklyn, NYC for an unforgettable night.

Masha and Nadya addressed the press again last night before the concert (video below), where they touched on a variety of issues including the Olympic games, their imprisonment and the future of Pussy Riot.

On the Olympics, Nadya called for a variety of boycotts:

This can be an active boycott, where you stage protests and demonstrations and so-on and so-forth, whether in Russia or here, whatever form you want to give them. You can even do a Pussy Riot performance because anyone can be a member of Pussy Riot.

Or you can hold a passive boycott, which means not going to Sochi, not writing about Sochi.

Discussing their imprisonment, Nadya said, “We realized we cannot be indifferent to things that are going on in the prisons, which is why right now we’re aiming to create a human rights organization called ‘Zone of Law’ and to also involve other international human rights organizations in observing the human rights situation in Russian Prisons.”

When asked about the future of Pussy Riot, the women explained that Pussy Riot was not limited to themselves or their original bandmates.

When we were jailed Pussy Riot immediately became very popular and widely known,” Masha said. “And it has turned from just a group into essentially an international movement. Anybody can be Pussy Riot. You just need to put on a mask and stage an act of protest against something in your particular country, wherever that may be, that you consider unjust.

The pair did not perform at the concert, but rather were introduced by Madonna who had vocally supported the band during their trial and subsequent imprisonment.

They were welcomed with a standing ovation before delivering an impassioned cry for the crowd to join them in fighting for the freedom of several Russian protesters who have been jailed since a May 6, 2012 protest against Putin in Moscow.

The concert itself was a star-studded event, featuring performances by Imagine Dragons, Ms. Lauryn Hill, Tegan and Sara, Cold War Kids, Colbie Caillat, The Fray, Cake, Blondie, Sir Bob Geldof and the Flaming Lips with Yoko Ono.

The theme of the night – emphasized in a video featuring Sting – was passing the torch of using music to help in the fight for justice from older artists to newer artists.

This, of course, is something Pussy Riot embodies particularly well. They have managed to combine the spirit of old punk protest with new technologies by sharing their protest set pieces online and over social media. And as Masha and Nadya made clear last night, we have not heard the last of them.
